Phone Story, an iOS game designed to highlight workers rights issues in the supply chain and production of Apple's iPhone, has been removed from the App Store due to a violation of Apple's review guidelines.

The game, from Every Day The Same Dream team MolleIndustria, consists of a series of four mini-games "that make the player symbolically complicit in coltan extraction in Congo, outsourced labor in China, e-waste in Pakistan and gadget consumerism in the West," according to the official web site.

The cited guidelines prohibit apps that "depict violence or child abuse," "present objectionable or crude content," "contain false, fraudulent of misleading representations" or fail to "comply with all legal requirements."

Apple's App Store guidelines include many other provisions limiting the type of content that's acceptable in apps, including prohibitions against apps that criticize religion, include excessive erotic or violent content, or that contain "offensive or mean-spirited commentary."

Other content distributed by Apple, including books and movies and TV shows sold on iTunes, are not subject to the same guidelines.
